To all whom t may concern Be it known that l, CYRUS T. HANNA, a vcitizen' of the United States, residing in Philadelphia, Pennsylvania, have invented certain improvements in Distilling Apparaset forth inthe above entitled application can be carried out; the object of my invention being to provide an apparatus in which il can ei'ect the removal of a greater percentage of the undesirable materials condensable at high temperatures from the vapor whereby I am enabled to obtain a purer product than has been produced in the operation oi' methods or apparatus heretofore in use. These and other features of my invention will be more fully pointed out herein.- after, reference being had to the accompanying drawings, in which:

Figure 1 is a front elevation, partly in section, of a distilling apparatus embodying my invention; Fig. 2, is a side elevation of the structure shown in Fig. 1; Fig. 3 is a sectional view on an enlarged scale of the upperportion of the apparatus shown in sectional views illustrating details of my invention. 'l

In carrying out the improved method or process of distilling in the use of the iinproved apparatus forming the subject-inatter of my present invention, and as set forth in my application and patent before referred to, l separate from the spirit vapor coming from the still, which may be a pot still, a

chambered still, a continuous still, or a still of any other suitable type, all oi the undesirable materials condei'isable at high tempcratiires, before the portions designed to be recovered as the final product and condensable at low temperatures are liqueiied, and either re-distill the liquid containing such undesirable materials, or dispose oi it in any suitable manner out of contact with the puritied and low temperature condensation product which I desire to obtain as the finished product from the operation of my improved method or process. 1

ln the use of my improved apparatus, the vapor is conducted in a vertical column through special forms orD internally disposed chambers which are so arranged and constituted that the vapor must pass out of one chamber through small apertures in thewall of the same having entangling means, then into the next succeeding higher chamber through apertures of similar character in the wall of the same having entangling means; such sinuous flow of the vapor being continued to a certain height and then diverted to a series of horizontal elements of substantially the same' character, in which the vapor is passed in and out of apertured chambers in the same manner in which such vapor is passed through the chambers of the vertical column and from the horizontal elements, in which some of the spirit purified to the extent desired may be condensed, the vapor is discharged; 'further condensation being eliected in an ordinary form of condenser situated below the horizontal chambers, and to which the vapor, with any condensation thereof, isdirected.

In the horizontal chambers referred to, l may introduce a heating medium for the purpose of maintaining a high temperature to sustain the low temperature condensation products in a vaporous condition therei i, or lif the operation of the apparatus is such that the removalA of the desired quantity of iinpurities has been or can be effected in the vertical column, l` may introduce a cooling medium into the horizontal elements. ln either instance, such heating or cooling medium may be in the form oi air, steam or gas. 'i also provide means for dripping fluid upon the exterior surface of the horizontal'eleinents, which fluid may be hot or cold water, as may best fulfil the object sought' to be attained, which depends entirely upon the character of the vapor dis` charging into the horizontal elements, and whether or not l desire to continue it in a substantially vaporous condition until it reaches the final condenser for the iiuished spirit disposed exteriorly of said horizontal elements.

An essential feature of my invention resides in the construction l have adopted for conducting the vapor from the heating vessel whereby l'. am enabled to condense the undesirable materials which liquefy at temperatures diiiering from and higher than that required to liquely the purified spirit vapor; a further feature being the provision of means for introduchiggaseous or vaporous bodies, hot or cold, into the horizontal vapor conductor, as mav be necessary to raise or lower the temperature therein to inl sure the condensation of the undesirable materials, and the carrying over of the condensable portions forming the finished product, or the condensation Within lsaid hori- .frontal elements of substantially all of the vapor discharged therein, when and at such times as said vapor may be of the character or purity desired to form the linished prodr not. Such condition may be augmented or created by the application of the external heating or cooling medium llowing over the outer surface or wall of said horizontal el ments ln the drawings herewith, l represents the heating'vessel of a suitable toi-.m of still, vihich may be of any approved type or de? sign, having an inlet 2 for the mash materiel, and an outlet or beak 3 for the vapor Adeveloped by cooking such mash. The vessel 1 may be heated to cook the mash by an internal steam coil Ll; the inlet and outlet connections or couplings :tor such coil being shown at 5 and G, provided with suitable valves 5 and 5g'. in some instances it maybe desirable to introduce live steam directly into the vessel l for contact with the material therein, and for this purpose the steam inlet connection 5 may be extended :is indicated at 7, and provided with a suitable valve 8, so as to be cut into and out of communication with the vessel 1. An outlet or drain fromthe vessel 1 is shown at 9, provided with a valve .9?.

The beak 3 communicates with a pipe or connection through which vapor from the vessel 1 passes to an elongated cylindrical column 11, lf desired; the apparatus may be operated under vacuum; a pump-12 being provided'for the purpose, and inl such instance the vapor may pass to the pump for delivery to the column 11. by way of a suitable by-pass 13; a valve 14; being employed to control the iiow of vapor from the vessel 1 td the column 1l and divert suoli vapor to the by-pass. The column 11 communicates by means of a suitable elbow section 15 with horizontally disposed vapor. conducting elements 16 placed soins distance above the vheating vessel l of the still, and through these conducting elements 16 the vapor is passed back and forth and finally discharged through a suitable pipe 17 to a condenser 18. From thecondenscr, the liquefied .spirit may pass through a tailboxI 19, havingthe usual testing' instrunientalities, and a pipe 20 lead- `ing therefrom to alrcceiving cistern 21, from which it may be drawn oli through a spigot 22, to barrels 23, or it may be barreled directly from the pipe 20.

rllie vapor conductors of the column 1l are fully shownv in the enlarged sectional views, Figs? et and 5. ',The column 11 may consist di cylindrical shells mounted one above another, within each of which are disposed a pair of cylinders 26 and 27, and each upper cylinder 26 may have a reduced outlet 28 at its lower end entering an enlarged cup 29 carried by the closed upper part of each cylinder 27. vThese cylinders 26 and 27 may have flanges 30 whereby 'they may -be held between the hanged ends 31 of the cylindrical shells 25, and they are apertured at 32, in the manner shown clearly in Figs. 5 and G, such apertures being preferably made by punching holes through the Walls of said cylinders. 'l he holes are relatively close together and the edges of said holes are left rough, just as made by the punch, in

order to afford additional means of entan-v glemem for the impurities condensable from the vapor at ,thigh temperatures. Other forms of oraminous or reticulated cylinders may be used, provided entangling meaiisare employed. rlhe vapor travels in the direction indicated by the arrows, and passes through the apertures in the cylinders 26 and 27 from the smooth surfaced wall of the same to the roughcned surface formed by the raised edges of said apertures, so that the condensable portion of the emerging vapor tending to flow with such vapor at the point of emergence is caught by the roughened edges and 4broken up; separating from such vapor and flowing down the walls of the cylinders.

Vapor from the heating vessel l, entering the column 11 passes into the lower inner cylinder 27, thence through the apertures oi" said cylinder to the space between its outer w'all and the wall of the cylindrical shell 25, thence to the cylinder 2G, whichrcommunicates directly with the' succeeding cylinder 27, and so on. By this means, the vapor is given a sinuous or circuitous path, and by" passing through the large quantity of small apertures oit' the several cylinders 26 and 27 in both directions and contacting with the entangling means adjacent said apertures, greater opportunity for removing the umpurities condensable at high temperatures is provided. y

The impurities forming the products of high temperature,condensation liow down the outer walls of the cylinders 26 and 27 and may pass through outlets from each cylindrical shell 25 of the main column 11,

which outlets are connected to a pipe 841 leading to a residue collector 35. A certain portion ofy these condensed impurities also pass down the inside of the cylinders 26 `and 27 and fill the cups 29, sealing the lower ends,

28 of the cylinders 26, and the overiloW from .said cups runs down the outside of said cylinders and collects in the bottom of the chambers formed by the cylindrical shells 25 andthe flanges 30 of the cylinders 26 and 27. The spirit vapor, therefore, While it may have to pass through films of, or in close contact with particles of, condensed vapor, does not have to pass through bodies of the saine as in the ordinary .forms of dephlegmators. The condensed impurities entering the pipe 34 from the outlets 33, ivhich iioW may be controlled by valves 36, may be returned to the heating vessel 1 of the still through a pipe 37, suitably valved at 38, or sent into the residue collector 35. In addition, if desired, certain portions of the condensed impure products collecting in the shells 25 may pass from vone chamber to.

the next vthrougfgh pipes 38a interiorly disposed with respect to the cylinders 26 and 27.

lllhen the vapor reaches the top ol the vertical column or conductor 11, it passes through the elbo\v connection 15 to a series of horizontal vapor conducting elements 1G of a design similar in all respect-s to those ot'y the vertical column; the outer walls of which may be cooled or heated, as the conditions may require, by Water dripping from perforated pipes 10, as shown in Figs. 1, 2 and 3, such water being supplied from a pipe al1. The pipes ll() are valved at 40 so that any one or all may be cut out, as desired. The impurities condensed in said conduct-ing elements 16 may be discharged through outlets Zl1, valved at 42, which outlets lead to horizontal 'pipes f8 connected to the pipe 34e, while thespirit vapor passes to the several conducting elements through the elbow connections all,` and from the lowest element it overilovvs into the pipe 17, and enters the condenser 18. i The conducting element-s 16 contain cylinders 2G and 27a of the same character as those indicated at 26 and 2'? and disposed within the cylindrical shells 25. .This is largely a matter of convenience to avoid the necessity of having several forms of the apertured cylinders7 since the portions providing the liquid seal When vertically arranged, have no real function when disposed in a horizontal position. ln some instances it may be desirable to introduce air, steam or other gaseous bodies into the conducting elements 16, and for this purpose l ipx- Ovide pipes 45 leading to said elements if'im a .pipe 4G leading from a suitable source of supply. As shown one pipe 4:5 communi- Cates with the upper elements 16, and lit will be understood that other pipes 4:5 may be connected to the other elements.v The pipes l5 are valved at 47 so that communication with the conducting elements may be controlled, and in some instances out off. One of the pipes 415 may communicate' With the 'the pipe 17 is connected.

-pipe 17 leading to the condenser. rl`he con-- denser comprises a cylindrical vessel having tubes L1-8 leading from a header ft2), to which The condenser vessel 18-is filled with water, supplied from a suitable source and this cools the tubes 1b. The drip from the conducting elements 1() is caught by a pan 16 and overflows via a pipe 17EL to the Water space of the condenser. By valving the several pipes for carrying oil' the impurities condensed at high temperatures, the discharge and direction olI discharge of such impurities may be changed at will, and any one ot the cylindrical shells 25 muy be drained independently ol:l the rest.

The heating vessel of the .still is provided Vwith tihe usual accessories, such as a contents gage 50, thermometer 51, vacuum gage 52, pressure gage 53, safety valve oil, vacuum valve 55, and other fittings, all of which are Well known and familiar to those skilled in the art and need nodetailed description herein.
